1. ScaleDB The cloud database Dial 712-338-7116 Access Code: 789-140-794

2. The Problem The cloud enables you to provision storage and compute power, but not database services…until now. ScaleDB “cloud-enables” open source databases, making them dramatically easier to provision, manage, scale and maintain in the cloud.

3. The Cloud is Disrupting Databases Shared Nothing Shared Disk 200-400 MB/s each 1.25 MB/s each 64 MB/s 1.25 MB/s each 1.25 MB/s each 1.25 MB/s each 8 Gbits+ 10Mbits 10Mbits 10Mbits 10Mbits 64 MB/s (Shared) Cloud Computing and Virtualization are two of Gartner’s Top 10 Disruptive Technologies 2008-2012 1.25 MB/s each

13. Customer Value Proposition Runs on low-cost cloud infrastructures (e.g. Amazon) High-availability Dramatically easier set-up & maintenance No partitioning/repartitioning No slave and replication headaches Simplified tuning Scales up/down without interrupting your application Data consistency Lower TCO

14. Cloud Vendor Value Proposition Supports Service Level Agreements High-availability (less downtime, faster recovery) Shifts relationship from dedicated hardware to SLA = profits Compatible with Virtualization (separates data/computing) More portable across computing infrastructure Enables dynamic allocation of computing and storage Reduces Management Overhead Reduced tuning and partitioning support No manual slave promotion or replication DBMS request routing is dynamic not fixed
